The assets and advantages of using the high quality synthetic diamond grinding wheels

Other information

Types of binding, grain size and examples of their use

- possibility of processing very hard as well as light materials

- high performance and quality of grinding

- high durability and constancy of the grinding wheel shape

- high efficiency

- favorable price and utility value proportion

Available is a wide range of grain size ranging from micro powder to very rough grain. The choice of the grain size cannot be

categorized. When making the choice it is necessary to take into account the purpose of the tool usage. There are three basic

operations: fining or frosting, fine grinding, rough grinding.

The synthetic diamond originates through the action of high pressure and temperature on the natural graphite. Through

various levels of pressure and temperature, different degrees of hardness of the synthetic diamond grain are achieved.

The requested grit size is then achieved through crushing, grinding, sifting and rinsing.

Diamond is the hardest known material on earth and in the hardness scale it is assigned number 10. Besides hardness,

this material is also exceptional for its good thermal conductivity and resistance to temperatures up to 700°C (1292°F)

and resistance to all kinds of chemical effect at standard temperatures.

Grinding surface of all diamond tools is prepared by the producer to be used directly. If the grinding potential of the diamond

tool decreases, we recommend to clean the working surface with an activating/revitalizing stone which we supply upon your

request.-1

The standard diamond wheels have the admissible peripheral speed 30m .

Essential for the successful use of the diamond tool is a good technical condition of the machine and usage of appropriate

coolants (Rotex, GS 600, water etc.)

1) Fining or matting

30-40, 20-30 µm small size grain, minimal roughness of the processed surface, minimal efficiency, minimal

removal of material

2) Fine grinding

270/325, 325/400 (MESH) medium size grain, standard grinding with medium roughness of the processed

surface, medium efficiency, medium removal of material.

The most frequently used grain size for the final processing of the surface prior to chemical polishing.

3) Rough grinding

60/70, 70/80 (MESH) large size grain, rough grinding with maximal roughness of the processed surface,

maximal efficiency, maximal removal of material.

The choice of bond depends on the type of the diamond wheel and the grain size

1)

a) The basic bond type used at manual processing is M2

This bond (M2) can be successfully used for wheels of any type. However, for the wheels of the types 1E1, 1EE1,

it is - in order to heighten the roughness - recommended to use different bond types (M3, M4), depending

on the grain size. For the wheels of the type 6A2 with small size grain it is in order to prolong the time between

trueing recommended to use the bond type M2.

b)

The second technologic operation: grinding of glass with further mechanical polishing in order to achieve glass

transparency (without acid polishing) - MB2.

For the operation of frosting the bond type MB1 is to be used. For the offer of the wheels with the bond type MB1

see page 21 of this catalogue.

2)

The highest efficiency of the diamond wheel designed for machine processing is achieved through the utilization

of the bond type M1.

For conditioning of the surface for effective mechanical polishing (fining), or for final processing of the surface

through frosting, the bond types MB1 and MB2 should be used.

The wheels with this kind of bond present a connecting link between common metal bonded diamond wheels and

the electrocorundum wheels. In many cases they are a fully adequate substitute. The wheels with the bond type

MB1 and MB2 allow for glass grinding (free of grinding burn) with higher efficiency than the common metal

bonded wheels (M2), and they keep the shape (angle or radius) better than the electrocorundum wheels. Diamond

wheels with these bond types are recommended for the following technologic operations:

The first technologic operation: grinding of glass with no further processing (the operation offrosting/mat-

ting). With this type of processing the surface remains frosted (non-transparent) - MB1.
